Javascript Image Encrypt Protector Tool

The JavaScript Image Encrypt Protector Tool is a versatile utility designed to enhance the security and privacy of images through seamless encryption and decryption processes, all within the JavaScript environment. This tool empowers developers and users to safeguard sensitive image data, control access, and ensure the integrity of transmitted or stored images.

Why is encoding images with Javascript necessary?

Encoding images in JavaScript can be an important factor in many different situations for many different reasons.

Safeguard Personal Information: If images contain personal or sensitive information, encryption safeguards privacy by preventing unauthorized access or misuse of the data.

Prevent Tampering: Image encryption can prevent unauthorized modifications to images, ensuring their integrity and authenticity. This is particularly important when verifying the source and content of images.

Access Control: Manage Access Rights Encryption allows for fine-grained control over access rights. Only users with proper authorization can decrypt and access the images, providing a way to control who can view the content.

Source Authentication: Control Origin Access Use encryption to control access based on the source. Only users from specific origins or with proper credentials can decrypt and view the images.

3. Encrypt the Image

image = document.getElementById('image');
let { data, map } = encryptImage(image);
                

4. Decrypt the Image

let data = decryptImage(image, encryptKey);
                

5. Example

let cookImage = async () => {
    image = document.getElementById('image');
    let { data, map } = encryptImage(image);
    image.src = data;
    let encryptKey = document.getElementById('encryptKey');
    encryptKey.value = JSON.stringify(map);
    document.getElementById('encryptButton').disabled = true;
    document.getElementById('decryptButton').disabled = false;
    document.getElementById('encryptKeyGroup').style.display ="block";
}
let deCookImage = async () => {
    image = document.getElementById('image');
    let encryptKey = document.getElementById('encryptKey').value;
    let data = decryptImage(image, encryptKey);
    image.src = data;
    document.getElementById('encryptButton').disabled = false;
    document.getElementById('decryptButton').disabled = true;
    document.getElementById('encryptKey').value="";
    document.getElementById('encryptKeyGroup').style.display ="none";
}
